Hi Peter, I just figured out how to get it working again. The patch seems to be based on a snapshot of the master branch somewhere at the end of January. On my machine I can reproduce the (very nice) results with these commands: git checkout dcbaa105aaa5494ba5eea296ca66df893bd5c9b6 -b

Hi I'll go to the workshop later an take a few pictures. I just realised we had a photo on our website. It's only a low resolution image, but I think it clearly shows the two vertical portals (the blue frames) and the rotary table in the centrer and a block of foam on it.

Hi Viesturs Since both of these options are possible, I think that the choice depends on: 1) Your skill and will to work on kinematics module; Hmm... I one compiled the millkins kinematics module (trivial kinematics extended by XY skew correction), and I'm more or less familiar whit C/C++.
